imo electrical components is a general term for all single components based on semiconductor materials, including diodes, transistors, field-effect transistors, and thyristors (the latter three are all three-terminal devices) made of various semiconductor materials. A transistor is a semiconductor device commonly used in amplifiers or electronically controlled switches. Transistors are the basic building blocks for the standard operation of computers, mobile phones, and all other modern electronic circuits. Due to their fast response speed and high accuracy, transistors can be used for a wide variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillators. Transistors can be independently packaged or occupy a very small area as part of an integrated circuit that can accommodate one hundred million or more transistors.

A thermopile is a pyroelectric infrared sensor, a device composed of thermocouples. It is widely used as a temperature detection device in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature detection. It consists of two or more thermocouples connected in series, where the thermoelectric potentials output by each thermocouple are superimposed on each other. Used to measure small temperature differences or average temperatures. Structure of a thermopile: The radiation receiving surface is divided into several sections, each connected to a thermocouple; connecting them in series forms a thermopile. Depending on the application, practical thermopiles can be made in wire-type and thin-film types, as well as multi-channel and array-type devices.

The rated current of the fuse element is not equal to the rated current of the fuse. The rated current of the fuse element is selected based on the load current of the protected equipment. The rated current of the fuse should be greater than the rated current of the fuse element and determined in coordination with the main electrical appliance. The fuse mainly consists of 3 parts: the fuse element, the housing, and the support. The fuse element is the key component controlling the fusing characteristics. The material, dimensions, and shape of the fuse element determine the fusing characteristics. Fuse element materials are divided into two categories: low melting point and high melting point. Low melting point materials, such as lead and lead alloys, have a low melting point and melt easily. Due to their higher resistivity, they require a larger cross-sectional size when made into fuse elements, generating more metal vapor during fusing, and are only suitable for fuses with low breaking capacity. High melting point materials, such as copper and silver, have a high melting point and do not melt easily. However, due to their lower resistivity, they can be made with a smaller cross-sectional size than low melting point fuse elements, generating less metal vapor during fusing, and are suitable for fuses with high breaking capacity. The shape of the fuse element is divided into wire-type and strip-type. Changing the shape of the variable cross-section can significantly alter the fusing characteristics of the fuse. Fuses have various fusing characteristic curves and can be applied to meet the needs of different types of protected objects.

Optical measurement and control systems manufactured based on different principles of luminous flux acting on photoelectric components are diverse. According to the nature of the output quantity of the photoelectric component (optical measurement and control system), they can be divided into two categories: analog photoelectric sensors and pulse (switching) photoelectric sensors. Analog photoelectric sensors convert the measured quantity into a continuously changing photocurrent, exhibiting a single-valued relationship with the measured quantity. Analog photoelectric sensors can be divided into three major categories based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and light-blocking (beam obstruction) type. The so-called transmission type refers to placing the measured object in the optical path, where the light energy emitted by a constant light source passes through the measured object, and after partial absorption, the transmitted light is projected onto the photoelectric component. The so-called diffuse reflection type refers to the light emitted by a constant light source being projected onto the measured object, and then reflected from the surface of the measured object onto the photoelectric component. The so-called light-blocking type refers to the situation where the luminous flux emitted by the light source is partially blocked by the measured object, causing a change in the luminous flux projected onto the photoelectric component; the degree of change is related to the position of the measured object in the optical path. Photodiodes are the most common light sensors. The appearance of a photodiode is similar to that of a general diode. When there is no light illumination, it behaves like a ordinary diode with a very small reverse current, known as the dark current of the photodiode. When illuminated, carriers are excited, generating electron-hole pairs, known as photo-carriers. Under the influence of an external electric field, the photo-carriers participate in conduction, forming a reverse current much larger than the dark current, which is called the photocurrent. The magnitude of the photocurrent is proportional to the light intensity, so an electrical signal that varies with light intensity can be obtained across the load resistor.
